The Garden Outdoor Storage Box is big but it would not be suitable for anything other than very light items - it doesn’t even have a proper floor - just a thin plastic cover that is attached to plastic rails by plastic buttons. Photos of an adult sitting on top of the box lead one to expect something much stronger than the flimsy plastic construction offered. By the way - the only metal part of the box is a thin strip of metal fitted across the lid - hence the only thing saving the lightweight adult from collapsing the entire structure. I wanted a box that could carry something other than a few lightweight soft toys.
I did think it would be sturdier for the price payed but it looks good for now. I am going to see if the sun here will damage it this summer alone as I suspect it will.
